Abstract:

A field method to measure, year-around, the quantity and quality of leachate under irrigated crops has been developed. A specific objective was to evaluate percolation lysimeters as tools for measuring the quantity and quality of leachate in the field, both within and outside the growing season. Results will help relate irrigation management and scheduling strategies to potential leaching of soil water and associated contaminants into ground water.
